Anaerobic respiration occurs in human body inside

Options

A. Liver
B. Kidneys
C. Red muscles
D. White muscles.

Answer

**Step-by-Step Solution:**

1. **Understanding Anaerobic Respiration**:
- Anaerobic respiration is a type of respiration that occurs without the presence of oxygen (O2). It is important to identify where in the human body this process predominantly occurs.

2. **Identifying the Options**:
- The options given are:
- A) Liver
- B) Kidneys
- C) Red Muscles
- D) White Muscles

3. **Analyzing Mitochondria Presence**:
- Mitochondria are the organelles where aerobic respiration occurs. The more mitochondria present, the more capable the tissue is of utilizing oxygen for energy production.
- White muscles have fewer mitochondria compared to red muscles, liver, and kidneys.

4. **Determining the Role of White Muscles**:
- Due to the low number of mitochondria in white muscles, they rely more on anaerobic respiration for energy production. This is because they cannot efficiently utilize oxygen.

5. **Excluding Other Options**:
- The liver and kidneys have a high number of mitochondria and are capable of aerobic respiration, thus anaerobic respiration does not occur there.
- Red muscles also have a high number of mitochondria and primarily rely on aerobic respiration.

6. **Conclusion**:
- Based on the analysis, the correct answer is that anaerobic respiration occurs in the human body primarily in **white muscles**.

**Final Answer**: D) White Muscles
